Let's say you're a music fan and got a copy of live concert .mp4 movie from a friend. Or maybe you downloaded a MP4 music video clip of the funny scene from Internet. Or there are TV shows with MP4 extension in your media collections. Whatever the case may be, you sometimes may wonder how to extract the sound from the MP4 and convert it to a MP3 audio file on Mac /PC, so that you then can listen to the music on a MP3 audio player.

What is MP4 (mpeg-4, h.264) video format

MP4 (MPEG-4 Part 14) is a digital format standard for storing video and audio, as well as data such as subtitles and still images. It can hold high-quality, highly compressed digital video encoded by mpeg-4 or h.264, along with AAC, MP3 or AC3 audio. MP4 is popular on the Internet and supported by a list of different devices.

If you want to listen to the audio, then creating MP3 audio from MP4 would be the wise move, as MP3 is already the most commonly used audio on the planet at current that it's difficult for other audio formats to replace it.

While there are a lot of MP4 to MP3 converter you could try, we're going to focus on Video Converter.
